In this video, Jacob Daniluck outlines the key features of the high-density Gateway Nexus and explains why it’s ideal for a wide range of deployments. 

Overview

The Gateway Nexus is ideal for a wide range of deployments and stands out as a compact, powerful and cost-effective alternative to virtualized codec and server-based systems. It can be installed at the broadcast plant, or in hosted data center environments. It is engineered to natively support AES67, ST2110-30, ST2022-7, RAVENNA, Livewire+, NMOS IS-04, IS-05, IS-07 and Ember+. Additionally, a Dante card can be installed at purchase. Compliance with these standards ensures seamless integration into IP-based audio with vendors supporting these protocols.

Applications

Gateway Nexus connects over any IP network and is ideal for:

  • Hosted or data center environments requiring high channel density and low latency connections for live programming and communications applications
  • Audio contribution and managing multiple remotes
  • Network syndication of programming
  • Multiple Studio-to-Transmitter Links
  • Multi-channel links to remote studios (inter-studio links)

High Density Deployments
with Deterministic Performance

As the broadcast industry shifts towards centralized and remote production models for live broadcast applications, the codec’s DSP-based platform allows broadcasters to upscale infrastructure efficiently. The Nexus is purpose-built for hosted data center deployments, delivering 32 channels of full-duplex high-density AoIP audio. Unlike virtual codec solutions, it provides fully deterministic performance that is predictable, low-latency, and fully hardware-based. The Gateway Nexus will expand your encoding capabilities by providing a centralized hub for all your AoIP streams.

Redundancy and Remote Control

Maintain rock solid connections with multiple layers of redundancy and backup including:

  • Dual internal power supplies, dual Ethernet ports and dual AoIP ports
  • SmartStream PLUS hitless packet switching
  • Fuse-IP data aggregation
  • Alternative connection backup
  • Audio file backup
  • Icecast streaming client
  • FEC and RIST

Gateway Nexus is fully configurable through an embedded HTML5 Toolbox Web-GUI interface and is also fully controllable using Tieline’s Cloud Codec Controller. It also supports monitoring and alerts using SNMP and automated alarm notifications using Toolbox software.

Interoperability

Advanced features and support for a wide range of protocols combine to deliver consistent latency, predictable performance and operational simplicity, making it ideal for state-of-the-art broadcast networks.

The Gateway Nexus is interoperable with all Tieline IP codecs and it is also compatible over SIP with all EBU N/ACIP Tech 3326, 3347 and 3368 compliant codecs and devices. The codec is also fully AES67, ST 2110-30, ST 2022-7, Livewire+ and RAVENNA compliant for AoIP streaming. It also supports AES3 and analog I/O as standard. The optional Dante card delivers seamless operation using Dante Controller. It is also AMWA NMOS IS-04, IS-05 and IS-07 compliant for AoIP discovery, registration, connection management, and notifi cations, simplifying setup and confi guration of networked AoIP devices and systems. The Ember+ control protocol is also supported.
